Issue SmartGWT to 5.0 On Browser

I have Update the smartGWT to 5.0 it gives the Error in browser console
"Failed to execute 'write' on 'Document': It isn't possible to write into a document from an asynchronously-loaded external script unless it is explicitly opened".

I think , It have some issue with loading javascript files when compile .
Please suggest me some alternate solution for this issue.

Thanks in Advance .
